Game Freezes with combat.

[Mystero]

Played all day Sunday no issue. Computer did a windows update, Graphic card update, and a bios update. Now when I get in game, I can do trade skills, talk to NPC's, get buffs, sit in EC, zone, everything but when someone near me or if I enter combat game freezes. I get no sound nothing just picture freeze cant alt enter nothing. All I can do is alt Esc and have to restart comp. Anyone have any idea what happened do I need to do a full re install of game or did I miss a P99 update?
